Title: Flavonoid aglycone and glycoside cpds. purification - by selective adsorption on oxide, hydroxide or basic salt of divalent metals
Inventor: HIERMANN ALOIS DR PHIL
IPC: C09B61/00
Filed: 1976-07-26
Abstract: Flavonoid aglycones and glycosides are isolated from extracts by forming complexes of the flavonoids with metal ions. In this process, solns. of the flavonoids in organic solvents (which may contain small amts. of water) are subjected to column chromatography using as sorbents granular oxides, hydroxides or basic salts of divalent cations which (a) are insoluble in the organic solvent used, (b) are soluble in dilute acids and (c) have a pH of 7-13 in aq. suspension. One or more columns contg. different sorbents as defined above may be arranged in series. Impurities are washed from the column by elution with organic solvents in which the sorbents are insoluble, then the flavonoids are recovered by dissolving in dilute acids and isolating from the resulting acidic soln. Plant flavonoids have a favourable effect on the heart and blood vessels. The process is suitable for use on a technical scale. It gives smooth removal of impurities without loss of flavonoids.

Title: Automatic brake control for train - has variable proportional amplifier to control extra braking and stop train at set point on track
Inventor: HAHN KARL DIPL ING
IPC: B60L15/20
Filed: 1976-10-22
Abstract: The automatic brake control for the train has a programmed parabolic braking curve which stops the train at a selected point on the track. The actual speed and braking force are constantly compared with the programmed curve to generate correction signals for the braking. The correction control circuit has a variable gain proportional amplifier which increases its gain as the set point is reached. The lower gain at the higher speeds ensures a smooth braking control with a min. of hunting about the programmed curve. The braking control is suitable for goods trains in which the brake response time is slow, esp. when most of the braking comes from the engine.

Patent DE-2658597-A1 (DE)
Inventor: HATA MORINAKA
IPC: H03H9/10
Filed: 1976-12-23
Abstract: A vibrator unit for use in a timepiece comprises a vibrator mounted within a ceramic case. A glass lid is airtightly sealed to the ceramic case by means of a soldering washer soldered between opposing surface portions of the lid and case. The soldering washer consists essentially of 90Sn-10Au solder alloy which enables formation of the airtight seal at lower and/or shorter soldering temperatures than would be the case with conventional solder alloys thereby avoiding an increase in the equivalent impedance of the vibrator unit which would otherwise occur. As the equivalent impedance can be maintained at a low value, the vibrator unit can therefore be made smaller without adversely affecting the equivalent impedance which is maintained below 350 K OMEGA .

Title: Continuous monitoring for dust in clean gas duct - by taking continuous sample stream, heating and checking in semiconductor device
Inventor: WINDAU PETER VON DIPL ING
IPC: G01N27/12
Filed: 1977-03-28
Abstract: The dust content of clean air ducts is monitored by taking a continuous gas sample from the duct. This is then heated to a roasting temp. The presence of dust in the sample is determined by the decomposition gases thus formed. These are measured by passing the gas stream through a semi-conductor cell, the resistance of which can be measured. The temp. of the semi-conductor cell is set to correspond with the gas component being investigated. Any gases chemisorbed onto the surface of the semi-conductor cell are desorbed by heating the semi-conductor cell. Used for checking the gas quality of streams leaving dedusting equipment. Gravimetric methods are labour intensive, intricate and generally non-continuous. Process gives simple, maintenance free, continuous dust measurement with a reliable alarm when a specified dust level is exceeded.

Title: Rotary piston engine with stratified charge - has eccentric driven pump jet to give stratified injection for pilot flame
Inventor: MOUNT ROBERT E
IPC: F02B75/12
Filed: 1977-05-03
Abstract: The engine is of epithrocoid construction and has a fuel pump jet unit (40) receiving fuel from a low pressure source and a hydraulic booster to produce a stratified charge in the working chamber. The pump jet is a 'T' shaped housing containing a servo valve unit (70) a cylinder piston unit (72) a pump push rod (74) a flow regulator (76) and a jet nozzle (78). The boosted pressure enters via a union (60) to act on the piston cylinder unit (72). The pressure is transferred to the push rod which presses fuel from the flow regulator into the jet nozzle. The injection pressure is boosted to approximately 700 atmospheres owing to the surface differences between piston (100) and push rod (74). The pump jet is fitted adjacent to the spark plug so that the initial injection is ignited to act as a pilot flame for the main injection.
Patent DE-2725376-A1 (DE)
Title: Seat belt limiter mechanism related to body weight - has hydraulic piston operated variable position stop for fluid throttling needle
Inventor: GRAUPMANN ROLF ING GRAD
IPC: B60R22/28
Filed: 1977-06-04
Abstract: The seat-belt mechanism is operated by piston (20) fitted underneath the seat (1). A piston rod (19) and carrier plate (17) are connected to the seat by the intermediary of a spring (18). The piston (20) operates in a hydraulic cylinder (22) with its space connected through a channel (23) to a smaller hydraulic cylinder (24) with piston (26), piston rod (27) carrying a stop (16) on its end. When the user occupies the seat, the piston (20) is depressed and fluid from a cylinder (22) is discharged into a cylinder (24) pushing the first cylinder (26) outwards against the force of a spring (28). The position of a sotp (16) forms a variable gap (S) with the rear end of throttling needle (13). In case of sudden deceleration, the inertia of the user's body acts with a force on the seat belt (2) and consequently on a piston (6) operating in fluid-filled cylinder (10). The piston is pulled outwards at a simultaneous displacement of fluid through the needle (13). The flow of fluid through the throttle is proportionate to the amount of travel of the needle determined by the position of the stop (16), i.e. the gap (S).

Title: Hydrophilic polyacrylonitrile fibres with high shrinkage capacity - have core and mantle structure and are made by dry spinning a dope contg. a miscible non-solvent for the polymer
Inventor: REINEHR ULRICH DR
IPC: D01F6/54
Filed: 1977-12-30
Abstract: Hydrophilic fibres with a core and mantle structure are made from hydrophobic, fibre-forming synthetic polymers and have a shrinkage capacity of >=35%, a porosity of >=10% and a water retention capacity of >=10%. The fibres pref. have a strength of >2 cN/dtex and an av. pore dia. in the fibre core of is not >10000 angstroms. Pref. fibres are of acrylonitrile polymers contg. >=40 wt. % acrylonitrile, with a porosity of >=17%, a water retention capacity of >=20%, and a mercury density of is not >1.0 g/cm3. The fibres are made by dry spinning a dope contg. the polymer, a solvent for the polymer and an additive which is a non-solvent for the polymer but which is easily miscible with the spinning soln. and with water or other wash liq. which is a non-solvent for the polymer. Spinning is carried out under such conditions that very little of the additive is vapourised out of the fibres, and the additive is subsequently washed out of the fibres in a wash bath. The process prevents the additive from evaporating out during spinning gives hydrophilic fibres with a much higher shrinkage capacity than prior art.
